ABSTRACT:
For a slide closure 10 attached to a pouring vessel 2 which has a movable slide part 14 disposed between a bottom plate 12 and a discharge part 16, there is, in addition to a cylinder piston unit 24 acting on the slide part, which unit is dominant by way of a servocontrol block 26 by regulating arrangement 32, a vibrator 36 which is controlled by an oscillator 34. The vibrator 36 is switched into the connection between the cylinder-piston unit 24 and the movable slide part 14, and is in a position to oscillatingly drive the latter both in its closing position as well as in other positions and, indeed, in the same direction as the cylinder piston unit. A position generator 44 starts the oscillator 34 forcibly in the closed position.
